Embodiment 1

[0076] Citing the following specific data, and substituting the data into the steps and formulas, explain the effect of the following adhesion checker model JM-A170 / 65:

[0077]

example 1

[0078] In Example 1, for the JM-A 170 / 65 model, three tests were carried out, and the user-defined maximum strokes were: 130mm, 150mm and 170mm. Through the control of the logic limit switch, the measured actual maximum strokes are respectively: 128.5mm, 150.4mm and 169.8mm.

Abstract

The invention relates to a railway turnout close-fitting inspection device, in particular to a control method for controlling normal start and stop of a push rod of a test board of a close-fitting inspection device. According to the invention, original hardware equipment such as a travel switch, a displacement sensor, a digital display scale and the like is reserved, and meanwhile, the concept of a logic limit switch is introduced through software control, so that the defects of a traditional test board are effectively overcome under the double protection of software and hardware, and the test requirements are better met.

Description

technical field [0001] The invention relates to a close-fit checker for railway turnouts, in particular to a method for controlling the normal start and stop of push rods on a test bench of the close-fit checker. Background technique [0002] The close-fit checker test bench is mainly used to test the characteristics of the close-fit checker of railway turnouts, including parameters such as the horizontal driving force, displacement, and insulation resistance of the pulling in and out of the rod. When testing the action characteristics of the close-fit checker in the traditional test bench, it is necessary to set a travel switch at both ends of the stroke to control the normal start and stop of the push rod. Although this structure is simple in design and easy to implement, it also has the following defects: [0003] 1. The position of the limit switch needs to be adjustable to meet the needs of different models and different strokes; [0004] 2. It can only be tested for ...
